To allwhom it may concern: I

c It known that I, JOHN C. HA'EFER', a

oit-izeii of the United States, residing at Cove, inthe county of'Union'and State of I Oregon, have invented new and useful lniprov'ements in Snow-Shoes, of which the f oll'owing is a specificatioin This invention relates to improvements in snow shoes and has for its objectto pro- 'V1Cl8 asnow shoe constructed of some-light material, such as aluminum which is not susceptible to-changes of climate, and which obviates the necessity ofsubj-ecting the shoe to the drying process aft'er the'same has been used, as is the case in the ordinary Another object? o't the invention is to pro vide asnoy shoe of this character with a simple means for retaining the said shoe upon the boot of the wearer, the said means being adjustablciso as to accommodate the sectional view upon the line 33 of Fig. 1.

-Fig. 4- is a transverse sectional-view taken upon the line l-e-i of Fig. 1.

In the accompanying drawings the numeral 1 designates the improved shoe. This shoe is constructed in the form of any ordi nary snow shoe, having the curvedsides extending from the upturned portion ,2 and terminating in thereduced heel 3., The shoe 1, may if desired be constructed entirely of aluminum or some other suitable material which is notsusceptible to penetration by water or cold, but in the device illustrated in the drawings the sides of the aluminum top of the device are bent ClOWIlj wardly as clearly illustrated, by Figs. 1, 3 andfi: of the drawings. 'This bent portion may be provided, if desired, with. a reinforcement of some suitable wood as desig nated by the numeral 4:, and the spaces-between this reinforcement-are provided with a plurality of transversely extending bracing'niembers '5. The members 5 are pref; erably constructed of'a 'singlepieee of metal "a collar member 7.

bent upon itself to -pro vide;theyertically arranged longitudinal. nmuuier-andliav ing its free ends bentin opposite directionsto provide ofi'sets having mg itab i Openings,- adapted for the receptionof' i etaining ole ments whereby the saith-braces a'r'e' etlec= tively connected with the body 1 of the shoe. The body 1 ofth'e snow sh o'e is provided intern'zediate the said'braces 5: with a central opening designated the numeral The front wall providedbythe opening (3 is preferablycurved as i llustra td'in Fig; 1 of the drawings, while ts directly .-op'-. posite wall is arrangedfin a parallelj'plane with the brace 111e1nberS-5.=v Securedyto'the under face of the shoe.lwliIectly'ceHtraI of the opening 6 and projecting thereover,-.is -This member, .71 is adapted to provide a central bearingfora' transversely arranged shaft 8'. This lshaft 8 is mounted within suitable bearings 9;and 10 upon the opposite sides of theroin'forcement jab. and if desired the shaftmay extend a suitable distance beyond one of the ottsct' sides of the member 1; -The'oentralportion of this shafts extended upon either side of .the collar 7 is preferably provided with op positely inclined threads ll'and the said threads are adapted to engage similar threaded eyes 12 provided by a resilient substantially U sha'ped toe engaging member 13'. This member 13 is provided with a vertical outer wall left and an overlying wall 15, so as to providela suitable pocket WlliClL is adapted for the reception of the toe portion of the sole. of the boot of the person using the snow shoe.

The numeral 16 designates a centrally arranged longitudinally extending *rod which" is pivotally connected with the U-shaped member 13 as at 17. This rod- 16 has its outer or free end threaded for a suitable distanceas at 18, ahd the said. threaded portion is'adapted to engage within a threaded bore 19 provided upon the base of the boot.

heel engaging member 20. This member 20 comprises a; flattened base portion, having a semi-circular vertical walland the central upper portion of the said well 21' is preferably provided with an inturned lip 22', the latterj being adapted to engage the 'rear portion of the heel of theboot,

The numeral 23 designates a thumb nutwhich is adapted to engage withthethreads .18 of v the rods 16 whereby. the heel engag ingsmember 20 may be; adjusted jlongitudlnally' upon the rod l6, and it will be noted that when the heel'engaging member 20 is brought toward the boot toe engaging member 13 the lip 22 will indent itself within the heel of the said boot and the. wearer will be retained readily upon the snow sioe 1.

, From the above description taken in connection with the accompanying drawings, it will be noted that I have provided an extremely simple and-thoroughly effective device for the purpose intended, andwhile I have illustrated and described the preferred embodiment of the improvement, as it now appea-rs to me, minor details of constructhe shaft 8. 7

Having thus fully described the invention, what I claim as vnew is 1. In asnow shoe of the class set forth comprising a shoe proper constructed of a single sheet of suitable materlal, a transverse shaft secured to the shoe, a resilient boot toe engaging element mounted upon the shaft, a heel engaging member pivotally connected with. the toe engaging member, and means for longitudinally adjusting the heel engaging member.

2. In a device of the class described, a

metallic .body member having its sides downward ofi'set, a reinforcement for these downwardly extending offsets, trans? verse reinforcements for the offsets, the body of the member being provided with an opening, a transversely arranged shaft mounted in bearings and underlying the opening, said shaft being centrally provided -\v1th oppositely pitched threads a U shaped member having eyes provided with oppositely arranged threads engaging the threads of the shaft, said U-shaped member having its face formed with a pocket, a longitudinally extending rod pivotally connected with the U-shaped member, a semi-cylindrical member slidably mounted upon the rod, said semi-cylindrical member having 'its curved-edge provided with an upstanding wall,a forwardly projecting lip arranged centrally of said wall, and means for adjusting the memberlongitudinally upon the rod.
